Sometimes user might not expect .fbm directory to be auto-generated into FBX file's directory.

Thanks very much! Yes, it’s frustrated me at times that the SDK writes next to the source, which ought to be considered a R/O area. Looks like you might also have helped with non-ascii source files? Will verify and merge later today.

Yes. The fbxFileName is encoded as ANSI or Unicode in Windows. But FBXImporter::Initialize requires UTF-8 encoding. (For me, "Failed to load FBX file" if CJK path passed to command line.)

@shrinktofit About to merge this, but now I'm thinking perhaps we should improve the default behaviour? For example:

• --fbx-tmp-dir-mode={auto/sdk/explicit}:
  • auto is default, and means call e.g. boost::temp_directory_path()
  • sdk is current behaviour
  • explicit requires --fbx-tmp-dir switch, as per your PR
